Проеверьте моя сочинение на наличие ошибок,пожалуйста.
Dear Tom,
Hi! How are you?I've been so worried about you since you started to pass the exams.By the way,how did they went?I hope you copied with them.
In the last letter you asked me about camping.I really want to come with you.But when and where are you going to go? I am going abroad in July,so I offer to go in the first week of August.
What about camping equipment,I have some of them on a garage.I have a tent,a brazier and a tree boat.Maybe my father has some other things,I will ask.
Who is coming with us?Can you send me a list of all their email addresses?Write back!
